I cannot consider it a bug and I prefer to open a suggestion.
While translating I tried to understand this sentence. What do you mean by remove links? does this option remove links into the thread?
I have finally discovered that it removes redirection notices or redirection links from one forum to another when you move a thread.

Wouldn't the proposed phrases be easier to understand?
